如何在mysql數據庫laravel中存儲數組數據？

Question

我收到錯誤Trying to access array offset on value of type int

下面是我的 controller 用於將數組數據存儲到數據庫中

    for ($i = 1; $i < count($request->sanitation_point_id); $i++) {
        $sanitation_points[] = [
            'daily_log_id' => $daily_log->id[$i],
            'sanitation_point_id' => $request->sanitation_point_id[$i]
        ];
        SanitationDailylogRelation::create($sanitation_points);
    }

Answer 1

數組索引從零開始，將循環初始變量更改為 0 ( $i = 0; )

完整代碼：

for ($i = 0; $i < count($request->sanitation_point_id); $i++) {
    $sanitation_points[] = [
        'daily_log_id' => $daily_log->id[$i],
        'sanitation_point_id' => $request->sanitation_point_id[$i]
    ];
    SanitationDailylogRelation::create($sanitation_points);
}

或為了更好的處理：

for ($i = 0; $i < count($request->sanitation_point_id); $i++) {
  if(isset($daily_log->id[$i]) && isset($request->sanitation_point_id[$i]))
  {
    $sanitation_points[] = [
        'daily_log_id' => $daily_log->id[$i],
        'sanitation_point_id' => $request->sanitation_point_id[$i]
    ];
    SanitationDailylogRelation::create($sanitation_points);
  }
}

Answer 2

嘗試這個

for ($i = 1; $i < count($request->sanitation_point_id); $i++) {
        $sanitation_points = [
            'daily_log_id' => $daily_log->id[$i],
            'sanitation_point_id' => $request->sanitation_point_id[$i]
        ];
        SanitationDailylogRelation::create($sanitation_points);
    }
